I have a serious question. How do you distinguish between peculiarities of normal sight and actual auras? For example, due to retinal fatigue, staring at any object will create a transparent ‘aura’ around it. This is due to fatigue and the minute constant movements of the eyes which make this ‘imprint’ seem to expand around the object. Retinal fatigue will also produce a colours complementary colour around the object in the same method as above (giving rise to a coloured ‘aura’).
How do you know when you are actually seeing an aura, or just retinal fatigue? Frequent staring at objects and producing this phenomenon causes it to happen much more quickly (conditioning the brain to notice such symptoms much quicker than the ‘default’ setting) – so having them arise instantly (as they do in me) isn’t an indication of one over the other.
I’d be interested to hear from someone versed in auras say how they distinguish between these. I am genuinely interested in this.
